Implementing the Handler and Getting a Handle to the Transaction

The handler function for the plugin’s parent continuation is implemented as follows:

  1. static int
  2. auth_plugin (TSCont contp, TSEvent event, void *edata)
  3. {
  5.      TSHttpTxn txnp = (TSHttpTxn) edata;
  6.      switch (event) {
  7.      case TS_EVENT_HTTP_OS_DNS:
  8.           handle_dns (txnp, contp);
  9.           return 0;
  10.      case TS_EVENT_HTTP_SEND_RESPONSE_HDR:
  11.           handle_response (txnp);
  12.           return 0;
  13.      default:
  14.           break;
  15.      }
  17.      return 0;
  18. }
